The tube container 1 is the same in all of the views of the drawings, and is composed of known lflexible non-resilient material forming a. compressible and collapsible vcontainer from which the contents are to be ejected by pressure applied to thetube or container at a distance from the discharge In all of the views of the dran-ings other than Fig. 11, the end 2 of thc tubo is formed l.

with an exteriorly threadedl nozzle 3 onto which all forms of the invention may be detachably screwed other than the form shown in Fig. 11. In Fig. 11, the end 4 of the tube 1 is formed with an exteriorly and interiorly threaded nozzle 5.

The invention shown in Figs. 1 and 2 comprises a bodyA 6 of substantially stili and inflexible material having at one end an interiorly threaded cylindrical extension 7 designed and adapted -to be screwed onto and from the nozzle 3. The body 6 has therethrough a longitudinal passage 8 through which the contents of the collapsible container tube 1 may be ejected. A valve seat 9 is formed around the passage 8 at the outer end of the body 6'and is opened and closed -by a valve 10 located at the outer end of said body 6 and movable into and out of contact v with the valve seat 9. A valve stern 11 has its outer end attached to the valve "-10. The valve stem 11 extends through the passage 8 and through a guiding spider 12 that is attached to the inner end of the body 6 within the tubular extension 7. A spring 13 is mounted around the inner portion of the stem 11 and has its outer end abutting against the spider 12 and its inner end bearing against a washer 14 secured on .the inner end of thel stem 11, so that the energy of said spring isvutilized to actuate the valve 12 to closed position against the seat 9 and to hold said valve yieldingly in said closed position. The body 6 is provided with a. peripheral ribbed or knurled portion 15 that may be conveniently and effectively engaged between the thumb and one of the lingers in order to operate the body 6 to screw the same onto and from the threaded nozzle 3.

When it is desired to discharge any of the contents of the tube container1, sullicient pressure is applied to said container to cause the contents to press against the inner side of the valve 10 and force said valve away from the seat 9. The contents may then pass through the outlet opening around-the valve 10 in tubular form. When pressure is removed from the tubular container 1,l the spring 13 will close the valve and will yieldingly hold said valve in closed position.4

The device shown infFig. 3 comprises an angular tube 16 having one end screwed onto the nozzle 3. A cylindrical body 17 is screwed on the outer end of the angular tube 16 andis formed at its outer end with an opening surroundedby a valve seat 18. A valve 19 is arranged to engage the valve seat 18 to close the opening. A valve stem 20 has its outer end attached to the valve 19 and itsinner portion extending through a guiding spider 21 secured to the inner side of the body 17. A spring 22 surrounds; the valve stem 20 and has its outer end engaging the spider 21 and its inner end engaging an abutment 24 secured on the inner end of the stem 20.V This spring 22 is effective to close the valve 19 after each opening operation thereof and to hold said valve yieldingly in closed posltion.

ment in attaching and detaching the devlce.

A tubular member 28 is exteriorly threaded at its inner end so that said member may be screwed into and out of a threaded hole in the body 25. A circumferential knurled portion or series of ribs 29 constitute an abutment to engage against the end of the body 25 to limit inward movement of the member 28.

The outer end of the member 28 is formed with a valve seat 30 around -the opening through said member. A valve 31 is movable to and from the valve seat 30 to close and to open the passage through the member 28. A valve stem 32 has its outer end attached to the valve 31and its inner portion extending through a guiding spider 33 attached to the inner end of the body 25. A spring 34 is mounted on the stem 32 and has its outer end engaging the spider 33 and its inner end engaging a washer l35 secured to the inner end. of the stem 32; This spring 34 acts to closek the valve 31 after each opening operation thereof and to hold said valve yieldingly in a hole through the stem 32. This pin 37,

by engagement against the flange 36, .limits extent of outward movement of the valve 31. To prevent the .valve 31 from openlng,

the member 28 is unscrewed a distance to bring the pin 37 into engagement with vthe flange 36 and thus prevent further movement of the valve 31.

It will be understood that the valve 31 will open under pressure of the contents of the tube 1 in the manner described above in reference to Figs. 1 and 2.

The device shown in Figs. 7 and 8 comprises a body 38 having at one end an interiorly threaded cylindrical extension 39 designed and adapted to be screwed onto and from the nozzle 3. A tubular member 40 has its inner end exteriorly threaded and is screwed into a threaded hole in the body 38, a circumferential knurled portion or series of ribs 41 contacting with the outer end of the designed and arranged to seat against the spring 45 projecting inwardly from a r-'mg 46 attached to the inner end of the body 38. This spring 45 engages an abutment 47 on `the inner' end of tlie stem 44 and is eiective to move the valve 43 to closed position after each opening of said valve and to hold said valve Ayieldingly against the seat 42. The valve 43 will yield to the pressure of the contents of the tube 1 and will open to permit discharge of said contents in the manner that is now understood from the preceding description.

The construction shown in Figs. 9 and 10 comprises a tapered body 48 having an internally threaded portion 49 at one end and a valve seat 50 at the opposite end. The internally threaded portion 49 is designed and adapted to be screwed onto and from the nozzle 3. The body 48 is formed with a circumferential polygonal portion 51 for manual engagement in attaching and detaching the device.

A valve 52 is designed and arranged to seat against the valve seat 50 Kto close the opening through the body 48. A valve stem 53 has its outer end attached to the valve 52. A spring- 54 surrounds the inner end of the stem 53 and has one end bearing against a shoulder 55 within the body 48 and the opposite end engaging the inner end of the stem 53. This spring is effective to close the valve 52 after the same has beenfopened, and to hold the same closed, but will yield to the pressure of the contents of the tube 1 when pressure is applied to saidtube.

.The mode of operation of this valve will be understood` from the description of the preceding views of the drawings.

The arrangement shown in Fig. 11 comprises an externally threaded sleeve 56 screwed into the nozzle 5 and having on its outer end an abutting Hange 57 engaging the outer end of said nozzle 5.` A valve 58`seats against a valve seat 59'at the outer end ofthe sleeve 56 and constitutes a closure for the passage through said sleeve. A spring 60 has one end engaging the sleeve 56 and the opposite end engaging the inner end of a valve stem 61. The outer end of the valve stem 61 is attached to the valve 58, so that the spring 60 isl effective to hold said valve 58 yieldingly against the seat 59. The operation of this valve 58 will be understood from the preceding description.

The construction shown in Figs. 12 and 13 comprises a body 62 detachably screwed onto the nozzle 3 and having a circumferential polygonal portion 63 for engagement to operate said body. The outer end of the body 62 has a lateral opening into which an externally threaded sleeve 64 is screwed. The sleeve 64 has on its outer end a circumferential Bange 65 that abuts against the body 62. A valve 66 cooperates with a valve seat 67 at the outer end of the sleeve 64 to close the opening through said sleeve. A 'stem 68 has its outer end attached to the valve 66 and its inner' end attached to the inner end of a sprin 69. The o posite end of the spring 69 a uts against tIile sleeve 64. Said spring is effectiveA to hold the valve 66 yieldingly aga-inst the valve seat 67. The operati'on of this Valve 66 in openingand closing the opening controlled thereby will be understood from the preceding'description.

The device shown in Figs. 14 and 15 comprises a cylindrical member including an internally threaded inner portion 7 0 screwed onto the nozzle 3'and an internally threaded outer portion 71.' This member is formed with a polygonal circumferential portion 72 for engagement in attaching and detaching the device. A sleeve 73 is screwed into the threaded portion 71 and lhas at its outer end a. circumferential flange 74 for enga ement in screwing and unscrewing the sleeveA 3. A valve 7 5`engages a valve seat 76 at the outer end of the sleeve 73 to open and close the passage through said sleeve. A stem77 has its outer end attached to said valve and its inner end attached to a twisted spring 78 projecting from a ring 79 clamped between the nozzle 3 and the member 7 0--71. v The sleeve 73 may be screwedoutwardly to.an extent to place the twisted spring portion 78 'under considerable tension sufficient to hold the valv-e 75 seated against the seat 76 so that the valve will not accidentally open.

The construction shown in Fig. 16 comprises a valve 79 designed and arranged to seat against a valve seat 80 at the outer end of the nozzle 81 which is formed integral with the container end wall 82.
